The operator admin sync now also takes homeserver admin away. It records
each user id it sends `make-user-admin` for in
`operator-matrix-admins.json` under the controller's state directory
(written to a temporary file and renamed over it; a missing file is an
empty set). On each pass, a recorded account that is no longer in
authelia's `admins` group but is still joined to `#admins:<server>` is
sent `!admin users force-leave-room <user> <admin room id>` as `@swarm`,
over the same `/_matrix` path the grant uses. Leaving that room is what
ends tuwunel admin.
It never revokes an admin it didn't grant, `@swarm`, tuwunel's server
user (`@conduit:<server>`), an agent's account (the store's
`hive-agent-*` cert roles, the same roster the agent account mint uses),
or anyone in the new `services.hyperhive.swarm.matrix.adminSync.ignoreUsers`
list. That list reaches the daemon as
`SWARM_CONTROLLER_MATRIX_ADMIN_SYNC_IGNORE_USERS`. It also never sends a
revoke that would leave `#admins` with no member besides `@swarm` and the
server user.
A revoke is sent at most once per account per controller process, like a
grant. A recorded account that is out of both the group and the room is
dropped from the file.
Closes#4799
The admin-room command stays in #admins' history, so a grant tuwunel
ignores must not be re-sent every five minutes. The controller now
sends `make-user-admin` at most once per operator per process; an
operator still missing from the room on a later pass is logged as
"make-user-admin for an operator failed to take" and left alone until
the controller restarts. The cap lives in the pure `plan()`.
swarm-matrix-client's `user_exists` and `joined_members` read their
responses through pure `profile_verdict` / `joined_verdict`, the shape
`whoami` / `whoami_verdict` already has, with every branch tested: only
M_NOT_FOUND is "no account", and a 403 or a list without `joined` is an
error rather than an answer.
The bridge's handling after authentication moves into `respond()`,
which takes the config and write lock instead of the whole AppState, so
a test can drive ListOperators through the real request path and see
the 403 without an HTTP client or an authelia.
docs/integrations/matrix.md no longer says @swarm is the only homeserver
admin.
swarm-authelia-bridge gains ListOperators, the usernames in authelia's
operator group (`operatorGroup = "admins"`, passed in from
swarm-authelia.nix). Unlike the two agent verbs, which admit any active
token, it answers only the client named by
SWARM_AUTHELIA_BRIDGE_OPERATOR_READER_CLIENT_ID (swarm-controller's
queueClientId) and returns 403 to every other active token: authelia
issues machine tokens to every hive and its agents as well. The bridge's
introspection now models `client_id` to make that check, the same way
swarm-nats-auth's does.
swarm-controller runs a grant-only pass at start and every five minutes:
read the group, map each username to the account an SSO login lands on
(tuwunel lowercases `preferred_username`), skip anyone already joined to
`#admins:<server>` (tuwunel's definition of admin) or without a matrix
account, and send `!admin users make-user-admin <user>` there as @swarm
with the swarm appservice token. Nothing is ever revoked: tuwunel has no
command for it (#4799).
The admin-room calls (alias, joined members, profile, send) go into
swarm-matrix-client next to whoami, keeping its no-body-in-errors rule.
Closes#4585
